Abstract

NEW MATERIAL:A cyanodihydrophenanthrene derivative of formulaI(R is 1W8C alkyl or acyl).
EXAMPLE: 2-n-Hexyloxy-7-cyano-9,10-dihydrophenanthrene.
USE: A liquid crystal compound. It has strong positive dielectric anisotropy, and is especially promising as a component constituting a liquid crystal composition for a twisted nematic liquid crystal element. It has high stability to moisture, air and light, and exhibits translucent white color as the liquid crystal state.
PROCESS: The compound of formulaIis prepared, e.g. from the compound of formula II through the intermediates of formula III, formula IV and formula V.
